Derivatives of coumarins, cinnamic acid and tyramine from leaves of Limonia crenulata. International Journal of Research in Phytochemistry and Pharmacology, 3(1): 9-12.http://hdl.handle.net/10321/915The present research was designed to isolate the Coumarins, Cinnamic acid and Tyramine from Leaves of Limonia crenulata . N - benzoyl tyramine and 2,4 - dihydroxy - 3 - methoxy cinnamic acid were isolated for the first time from the leaves of Limonia crenulata. Known compounds stigmasterol, daphnetin - 8 - methyl eth er and umbelliferone were also recovered by chromatographic separation techniques. Five compounds were isolated from the acetone extract of Limonia Crenulata and their structures were confirmed from spectral evidence and comparison with literature values. The compounds included derivatives of coumarins, cinnamic acid and tyramine.4 penLimonia crenulataCinnamic acidTyramineCoumarinsArticle
